This 1.2ct lab-grown heart sits in the classic one-carat band, graded E colour (colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG831679846 or 831679846. Listed at 13 retailers as of October 29, 2026, with prices from $263 to $1,342, a $1,079 spread on the same certified stone. Brilliant Earth lists it at $1,342. Cut grade matters more than carat or clarity for visible brilliance. If you can shift budget toward an Excellent or Ideal cut, do it before chasing higher colour or clarity.
